New Scientist: Water, water everywhere

Electricity and water form the lifeblood of our cities. As populations grow and we switch to renewable sources of power, neither will be as plentiful as they are today. In the first of three articles, produced in association with IBM, New Scientist explores how to handle these precious resources in smarter ways. This week, Fred Pearce visits Singapore, which has become the world leader in catching, using and recycling water.

Thinking about Dunedin, how would you answer the New Scientist poll?

Which of the measures taken by Singapore would you most like to see adopted in your area?

– Damming river estuaries to create reservoirs
– Encouraging consumers to use less water
– Prevention of serious water leaks
– Recycling water from surface runoff
– Desalination of seawater
– None of the above. Everything’s fine

    What are the resource consent rules regarding water tanks in Dunedin city? I believe that they vary, are easier to get for rural but there might be restrictions in some urban areas? Every house should have a rainwater runoff tank where feasible, for grey water use.

    That should also take load off the purification plant, storm drain system and not place any greater load on the sewerage system.

    There’s a major hole in the water tank process. Building Control at DCC takes no responsiility for the design, construction, or installation, of these. It is left to the ORC to give a resource consent, and they are limited to tanks over a certain volume.

    I agree entirely with you, Stu, that the installation of (or, at minimal, evidence of the investigation of) of greywater tanks should be a requirement for a Building Consent. That’s something that can be imposed by Building Control. It doesn’t currently fall inside the Building Act, but the powers of DCC are not limited to the Act.

    Sorry, I started off talking about water tanks. I did of course mean wastewater tanks when I was talking about Resource Consents.
